Stoichiometric polyelectrolyte complexes (PECs) of the strong polyelectrolytes poly(styrenesulfonate) (PSS) and poly(diallyldimethylammonium) (PDADMA) were dissociated dissolved in aqueous KBr. Water was added to dilute salt, allowing reassociate. After appropriate equilibration, these mixtures yielded compositions spanning (solid) coacervates (elastic liquid) solutions with increasing [KBr]. These defined by a ternary polymer/water/salt phase diagram. For coacervates, transient microphase...
Polyelectrolyte complexes are a fascinating class of soft materials that can span the full spectrum mechanical properties from low-viscosity fluids to glassy solids. This be accessed by modulating extent electrostatic association in these complexes. However, realize potential polyelectrolyte as functional materials, their molecular level details need clearly correlated with response. The present work demonstrates making simple amendments chain architecture, it is possible affect salt...
Skeletal muscle provides inspiration on how to achieve reversible, macroscopic, anisotropic motion in soft materials. Here we report the bottom-up design of macroscopic tubes that exhibit actuation driven by a thermal stimulus. The tube is built from hydrogel which extremely long supramolecular nanofibers are aligned using weak shear forces, followed radial growth thermoresponsive polymers their surfaces. hierarchically ordered exhibits reversible with changes temperature, much greater...
Silver ions were incorporated into titanium phosphate ultrathin films by an ion-exchange process conducted at 50 °C and room temperature. The silver dispersed homogeneously along the normal direction of film, as confirmed UV−vis spectroscopy X-ray photoelectron spectroscopy. In situ reduction NaBH4 produced nanoparticles embedded in film. particle size is dependent on temperature, where a higher temperature leads to larger size. silver-ion-exchanged are effective prohibiting growth...
High-flux filtration membranes constructed through scalable and sustainable methods are desirable for energy-efficient separations. Often, these criteria difficult to be reconciled with one another. Polymeric can provide high flux but frequently involve organic solvents in processing steps. Solubility of many polymeric media also restricts their implementation solvent filtration. In the present work, we report a simple high-throughput aqueous approach polyelectrolyte complex (PEC)...
Saline, lacustrine rift basins (SLRBs) can contain very productive shale oil plays, in which "sweet spots" are closely related to organic-rich intervals. However, organic matter enrichment the intervals within SLRBs and controlling factors have not been well-explored past research. In this study, well Pu6-65 Dongpu Depression of Bohai Bay Basin was systematically cored analyzed for basic geochemistry, trace elements, clay mineral content, original total carbon (TOC) understand relationships...
The properties of polyelectrolyte complexes, PECs, made from blended polycations, Pol+, and polyanions, Pol–, are routinely studied under conditions where they at least partially swollen with water. Water plasticizes transforming them an intractable, glassy, brittle state when dry to tough viscoelastic wet. In the present work supreme efficiency water, compared other solvents on a polarity scale, in swelling PEC is illustrated. Using poly(diallyldimethylammonium) poly(styrenesulfonate)...
Abstract Comparative analyses of petroleum generation potential, reservoir volume, frackability, and oil mobility were conducted on 102 shale cores from the Dongpu Depression. Results show has high organic matter contents composed oil-prone type I II kerogens within window. Various types pores fractures exist in shale, with a porosity up to 14.9%. The brittle mineral contents, extensive fractures, potential for due seepage capacity overpressure. Although at Well PS18-8 is relatively greater...
Abstract Combined with the actual geological settings, tight oil is that occurs in shale or reservoirs, which has permeability less than 1 mD and interbedded close to shale, including dolomitic oil. The Fengcheng area (FA), at northwest margin of Junggar Basin, China, made significant progress exploration (P f) Formation recently, indicates resources have good prospects. Whereas lack recognition hydrocarbon generation expulsion characteristics Permian P f source rocks results...
Nanotechnology in medicine has greatly expanded the therapeutic strategy that may be explored for cancer treatment by exploiting specific tumor microenvironment such as mild acidity, high glutathione (GSH) concentration and overproduced hydrogen peroxide (H2O2). Among them, responsive chemodynamic therapy (CDT) utilized Fenton or Fenton-like reaction to produce excess hydroxyl radical (·OH) destruction of cells. However, produced ·OH is easily depleted GSH tumors, which would undoubtedly...
A layer-by-layer adsorption and reaction method was developed for the preparation of titanium phosphate ultrathin films. By repetitive hydrated from aqueous Ti(SO4)2 solution subsequent with groups, films were fabricated. Regular film growth verified by UV−vis absorption spectroscopy quartz crystal microbalance measurements. The composition is mainly Ti(HPO4)2, as confirmed X-ray photoelectron FT-IR spectroscopy. as-prepared are uniform, highly stable, their thickness can be well controlled...
During the development of multi-layer tight sandstone gas reservoirs in Ordos Basin, China, it has not been easy to calculate accurately production each individual layer wells. However, allocation provides a vital basis for evaluating dynamic reserves and drainage areas wells remaining distributions layers. To improve accuracy reliability wells, new model was constructed based on seepage equation, material balance pipe string pressure equation. In particular, this introduced equation with an...
Although polymers are most often used within bulk materials, investigating their conformations and dynamics has long been a challenging endeavor in this configuration, particularly under external forces. Addressing this, we utilize single-molecule localization microscopy as powerful imaging tool to visualize bottlebrush poly(n-butyl acrylate) chains the state spherical indentation, quantitatively describing changes behavior of single polymer chains. We compare these experiments displacement...
